My most Boomer take is that I will not download an app or sign up for a patient portal.
I'd feel differently if there were a central or national US standard for EHR, but until then, it's paper or bust for me.

🤯 You can mousewheel-scroll the tabs in Firefox's tab bar! Had no idea you could do this and just stumbled into it today by pure accident.
Now that I am no longer fettered by the primitive chains of my screen resolution, I'm about to be an absolute menace to my 64 GiB.

First AWS, now Azure. It's going to be a month of hugops.
Currently seeing outages on:
* Azure Portal
* Azure Front Door
* Azure CDNs
DNS strikes again, maybe. Are you being similarly affected? Would love to hear what's up/down for you because the Azure status page is still mostly green.

In light of the upcoming SNAP suspensions in the US, it's worth pointing out that Walmart captures 25% of all SNAP expenditures: www.supermarketnews.com/grocery-tren...
Walmart brings in the most SNAP dollars, some 25% of all sales
But SNAP recipients overall are struggling, according to new data from Numerator

The NYT is running a story about how a certain mayoral candidate's name is hard to pronounce.
But English is the same language that has "onomatopoeia", "isthmus", and "Worcestershire". It can definitely make room for pronouncing Zohran Mamdani correctly.
I believe in you. Sound it out!

IMO, most status pages are implemented incorrectly.
Almost all of them run on the idea of "green until you report an incident".
It should really be "red unless you explicitly and periodically prove you are green" — heartbeats.

I leave an account with Wells Fargo open with a minimum balance, because every year or so they do something mega-illegal with my money, they get fined, and then I get a three digit USD class action settlement lawsuit.

Waking up to discover that AWS's us-east-1 is down at 03:00 ET, and my org got to sleep through it.
This is why I insist that building cross-region failover in important systems is great — not just because it's a good architectural idea, but because it's a great way to avoid having to get paged.

We have become "that house" and my food budget is in shambles because everyone is staying for dinner.

It is wild that we don't have "short-lived automatically deployed environment per branch" figured out as a default. It's the first thing I try to introduce in a new engineering organization/product/team because it's just such a massive productivity booster.

OpenAI recently released Sora 2, their new video model. I had access to preview it this past week.
Just to give you a flavor of the general capabilities, here's a zero-shot 15-second video I made (no editing, no revisions). Prompt in thread.

The more I talk to developers the more stunned I am at how little we are (as a community) leveraging the power of LLMs, and also how poorly we're using them now.
I feel like the median developer is using something like 1% of the available potential here. So much is being left on the table.
